Coil Amp.

[Grizzly]

Just thought i'd post this to show how Coil Amplifiers have shrunk in size nowadays https://www.youtube.com/watch?v=5PKM3Eo737E

I have a similar sort of thing fitted to my Race car and it made quite a difference to the longevity of the plugs (It also enabled me to run more Boost as the Spark is more stable)

All that said watching this video give an idea of the Interference you get as you wind the Ignition up (Listen to the camera as they turn on the Amp)
